The objective of this review is to outline the beneficial role of surfactants as corrosion inhibitors in the petroleum field. After an introduction and brief notes on fundamentals of surfactants, the article shows the most important corrosion problems in the oil industry and the effective role of surfactants to solve these problems. The reported mechanisms of corrosion inhibition by surfactants are also considered. Key results are extracted from publications covering the past 50 years. 相似文献

Alkyl and fatty acid glycosides have become of great commercial interest in general and specifically for the pharmaceutical,
cosmetic, and food industries. Natural surfactants are good sources for future chemical preparation of these glycosides. This
review article shows an astonishing diversity of natural surfactants that could be used in laboratories and industry. More
than 250 natural surfactants, including their chemical structures and biological activities, are described in this review
article. 相似文献

Silicone surfactants have been widely used in our daily life and many industrial fields on the basis of their unusual properties.
Only in the past decades has the use of silicone as a hydrophobic building block for the preparation of surfactants become
common. The recent trend to combine silicone, polyoxyalkylene and carbohydrate moieties in the same molecule has resulted
in a plethora of new compounds with new properties. The generic structure and surface activity of silicone surfactants are
reviewed in this article. Especially, the preparation, properties and application of carbohydrate-modified silicone surfactants
such as glucosamide-containing and glycoside-containing silicone surfactants are described in detail. In addition, the future
development of silicone surfactants is discussed. 相似文献

Sulfonated Gemini surfactants are a relatively new class of anion surfactants, composed of 2 or more sulfonated surfactant monomers connected by a spacer at or near the head groups through a covalent bond. In general, the sulfonated Gemini surfactants show better properties compared to conventional anionic surfactants including better surface activity, a lower critical micelle concentration, enhanced detergency, excellent compatibility with other surfactants, and better solubility in high ionic strength systems. This article reviews the synthesis of the sulfonated Gemini surfactants using different raw materials. Based on the existing information in the literature, new ideas are proposed for the synthesis and application of the sulfonated Gemini surfactants. 相似文献

FA amide glycosides are of great interest, especially for the medicinal and pharmaceutical industries. These biologically
active natural surfactants are good prospects for future chemical preparation of compounds useful as antibiotics, anticancer
agents, or for industry. More than 200 unusual and interesting natural surfactants, including their chemical structures and
biological activities, are described in this review article.

This article includes an updated review of the classification, uses and side effects of surfactants for their application in the cosmetic, personal care and pharmaceutical industries. Based on their origin and composition, surfactants can be divided into three different categories: (i) synthetic surfactants; (ii) bio-based surfactants; and (iii) microbial biosurfactants. The first group is the most widespread and cost-effective. It is composed of surfactants, which are synthetically produced, using non-renewable sources, with a final structure that is different from the natural components of living cells. The second category comprises surfactants of intermediate biocompatibility, usually produced by chemical synthesis but integrating fats, sugars or amino acids obtained from renewable sources into their structure. Finally, the third group of surfactants, designated as microbial biosurfactants, are considered the most biocompatible and eco-friendly, as they are produced by living cells, mostly bacteria and yeasts, without the intermediation of organic synthesis. Based on the information included in this review it would be interesting for cosmetic, personal care and pharmaceutical industries to consider microbial biosurfactants as a group apart from surfactants, needing specific regulations, as they are less toxic and more biocompatible than chemical surfactants having formulations that are more biocompatible and greener. 相似文献
